发耳隧道为贵州省六盘水至盘县高速公路的重点控制性工程,其贯穿于整个发耳矿区煤系地层,为高瓦斯隧道。由于隧道所处发耳矿区为煤与瓦斯突出矿区,因此隧道施工防治开挖工作面煤与瓦斯突出是隧道安全管理的重点。结合煤矿、铁路与公路施工的特点及相关行业规程、规范,提出了发耳隧道“四位一体”综合防突措施。 The Ear Tunnel is a key controlled project of the expressway from Liupanshui to Panxian in Guizhou Province. It runs through the coal strata of the entire ear mining area and is a high-gas tunnel. Since the ear mining area where the tunnel is located is coal and gas outburst mining area, the prevention and control of coal and gas outburst in tunnel construction is the key point of tunnel safety management. Combined with the characteristics of coal mines, railways and highways construction and relevant industry regulations and norms, put forward the ear tunnel “four in one” integrated anti-collision measures.
